Abstract
Classification of the types of pneumococci in endemic pneumonia was incomplete previous to and during the earliest part of our work. Originally group IV contained types IV to XXXII, and at least three different specific types were included in type II and two in type III. Since the more comprehensive classification of Cooper1and her co-workers has been accepted, the distribution of the types of pneumococci in endemic pneumonia has been studied in various parts of the world. These types have occurred in differing proportions, according to reports published in New York,2Boston3and San Francisco4and in Great Britain,5Germany,6Holland,7India8and South Africa.9 We have studied the 4,048 cases of endemic pneumococcic infection recorded during seven years, 1928 to 1935, at the Harlem Hospital. There were 2,708 cases of pneumonia in adults and 663 cases of pneumonia (primary) in children, a total of 3,371 cases.10
